But about two thirds of the way through the footage cuts to a video charting the development of Kim's nuclear weapons.

The film starts with the country's first medium range ballistic missiles under Kim Jong-un's grandfather, Kim Il-sung.

It then traces their development through the reign of his father, Kim Jong-il, before arriving at the present day.

North Korea's missile development program has advanced at an extremely rapid pace since Jong-un inherited control of the country six years ago.

The acts, who took to the stage in Pyongyang earlier this week, included hula girls, solo artists, and a dancing troupe

The performance itself was attended by Kim and his most loyal subjects in the North Korean capital, but was then broadcast for the whole country to see

So far this year his regime has carried out 10 tests, double the amount carried out in any other year to date, eight of which have been successful.

Analysis of the missiles shows the North now possesses advanced targeting technology, as well as the ability to launch from submarines.

The final test, of the Hwasong-14 missile, is the most significant to date as it proves the North has inter-continental ballistic missiles, or ICBMs.

The newly developed missile flew 2,500km into space - roughly seven times the height of the International Space Station - on a vertical trajectory before splashing down in the Sea of Japan.

If fired horizontally, as a weapon would be, the missile would be at least capable of reaching Alaska - though some analysts believe the engines could have been cut out early during the test, possibly allowing it to travel further.

The Hwasong-14 is also capable of carrying nuclear warheads, though it is not clear if North Korea has yet developed devices small enough to be mounted.

As the acts performed a video behind them charted the grim progress of the North's nuclear missile programme - which culminated in the launch of Hwasong-14 this month

Dancing troupes were just one of at least a dozens acts to perform at the concert celebrating North Korea's missile programme

South Korea has also said the North does not possess the technology to bring the devices back down to Earth successfully and on target.

The regime has made it clear for years that its ultimate goal is to develop a nuclear weapon capable of bringing destruction to America - though they insist it is only meant as a deterrent and to ensure their reign will not be toppled.

President Trump has previously vowed that Kim developing such a weapon will not be allowed to happen, before sailing an 'armada' of aircraft carriers and nuclear submarines into the region as a deterrent.

Trump also leaned hard on China to tighten sanctions on Kim's regime in an attempt to convince him to give up his weapons programme, but to no avail.

Meanwhile the President's advisers have repeatedly insisted that 'all options are on the table' when it comes to North Korea, raising the prospect of war.

Most analysts agree that Kim will likely develop a nuke capable of hitting most places in the US within the next few years, if he has not done so already.

North Korea's nukes - a timeline

THE PATRIARCH: KIM IL-SUNG (1948-1994)

1948: Kim Il Sung, a former guerrilla leader fighting against Japan's colonial rule, establishes the Democratic People's Republic of Korea in the northern half of the Korean Peninsula.

1950: Kim's army invades South Korea, triggering the three-year Korean War. The United States fights alongside South Korea while China backs North Korea.

Kim Il-Sung, Kim Jong-il and Kom Jong-un have all made it their mission to develop a nuclear weapon capable of ranging the mainland United States

1985: North Korea joins the Nuclear Nonproliferation Treaty. But the country doesn't allow inspections required by the pact, arousing suspicions that it's engaging in clandestine work to develop atomic weapons.

1993: North Korea announces its withdrawal from the Nuclear Nonproliferation Treaty, touching off an international nuclear crisis.

July 1994: Kim Il Sung dies of a heart attack at age 82. His son and longtime heir apparent, Kim Jong Il, takes power.

Kim Il-sung helped to develop some of the country's first ballistic missiles, along with overseeing its nuclear weapons programme

THE SON: KIM JONG-IL (1994-2011)

October 1994: North Korea and the United States sign a landmark nuclear disarmament deal in Geneva.

North Korea pledges to freeze and eventually dismantle its nuclear weapons program in exchange for international aid to build two power-producing nuclear reactors.

1998: North Korea stuns the region by firing a suspected missile over Japan and into the Pacific Ocean.

2002: Assistant U.S. Secretary of State James Kelly says North Korean officials admitted to having a secret nuclear weapons program during his visit to Pyongyang. The 1994 pact subsequently falls apart and a nuclear crisis flares again.

His son, Kim Jong-il, oversaw the development of the country's first intermediate-range missiles until his death in 2011

2003: North Korea attends Beijing-hosted disarmament talks that also involve Washington, Seoul, Tokyo and Moscow. The on-and-off talks continue until late 2008, producing two major now-stalled disarmament-for-aid deals.

July 2006: North Korea launches a three-stage rocket with a potential range of 6,700 kilometers (4,100 miles) but it fizzles after liftoff, according to U.S. and South Korean officials. North Korea has never acknowledged the launch.

October 2006: North Korea conducts its first underground nuclear test blast, citing "extreme threat of a nuclear war" from the United States.

Kim claimed to have tested the first ICBM, but no evidence of this was ever provided

THE GRANDSON: KIM JONG-UN (2011-present)

2012: North Korea puts a satellite in orbit with a long-range rocket. The United States, South Korea and others condemn the launch as a cover for testing long-range missile technology. It is the North's first successful satellite launch.

2013: North Korea carries out its third nuclear test.

January 2016: North Korea says it has conducted a hydrogen bomb test. It's the North's fourth nuclear test, but many outsiders are skeptical that it was a hydrogen bomb explosion.

February 2016: North Korea succeeds in its second satellite launch.

August 2016: North Korea fires a ballistic missile from a submarine that flies 500 kilometers (310 miles) before crashing into waters near Japan.

Kim Jong-un has overseen rapid development of North Korea's nuclear programme, carrying out 10 tests so far this year

Missiles launched from submarines are generally harder to detect than land-based ones.

September 2016: North Korea stages its fifth nuclear test, its most powerful atomic bomb explosion to date.

February 2017: North Korea tests a new midrange ballistic missile, the Pukguksong-2.

It says the missile used solid fuel, an advance that increases a weapon's mobility and makes it harder for outsiders to detect a coming launch. The North tests this missile again in May.

July 4, 2017: North Korea test-fires its first ICBM at an extremely lofted angle. The missile, called Hwasong-14, is capable of reaching Alaska and beyond if launched at a normal trajectory, according to outside experts.

After the launch, Kim says he won't put his weapons programs on the negotiating table unless the United States ends its hostility and nuclear threat.

Kim tested the first confirmed ICBM earlier this month which is thought to be capable of reaching Alaska
